The surface and volume crystallization of Fe
80–xV
xB
20 (x=6, 10, 20) metallic glasses, produced by the melt spinning method, have been investigated by means of exoelectron emission (EEE) and differential thermal analysis (DTA). A comparison of the results of the EEE and DTA measurements shows clearly that surface crystallization occurs at temperatures

200 K lower than volume crystallization. The activation energy for the surface crystallization is also distinctly lower than that for crystallization in the bulk.
